Description

Technical Field

[0001] The present invention belongs to the technical field of face recognition technology based on the Internet of Things, and in particular relates to a face recognition device based on the Internet of Things. Background Art

[0002] The Internet of Things refers to the use of various devices and technologies such as information sensors, radio frequency identification technology, global positioning systems, infrared sensors, laser scanners, etc. to collect real-time information on any object or process that needs to be monitored, connected, and interacted with, and to collect various required information such as sound, light, heat, electricity, mechanics, chemistry, biology, and location. Through various possible network accesses, it realizes ubiquitous connection between objects and objects, and between objects and people, and realizes intelligent perception, identification, and management of objects and processes. Face recognition is a biometric identification technology that identifies people based on their facial features. It uses a camera or camera to capture images or video streams containing faces, and automatically detects and tracks faces in images, and then performs facial recognition on the detected faces. This is a series of related technologies, also commonly known as portrait recognition or facial recognition.

[0003] In the existing technology, the use of facial recognition devices has greatly increased the practicality of the Internet of Things. Facial recognition devices are usually installed in the entrance passages of office buildings or shopping malls. People entering are scanned through the panel of the facial recognition device, so that the information of the people is collected, and then the control of people entering and leaving is achieved. However, the facial recognition panel is exposed to the environment for a long time, and a lot of dust and stains will accumulate on its surface, which will affect the accuracy of facial recognition. At the same time, in places with a large number of people, there will be more bacteria and viruses in the environment. Especially when the influenza virus is prevalent, bacteria and viruses will adhere to the surface of the facial recognition device panel. When staff adjust and wipe the equipment, they will easily come into direct contact with bacteria and viruses, making them susceptible to bacterial and viral infection, which will affect the staff's subsequent work.

[0004] Therefore, there is a need for a facial recognition device based on the Internet of Things to solve the problem in the existing technology that dust and stains affect the accuracy of facial device recognition, and that workers are susceptible to bacterial and viral infections when adjusting and wiping the equipment.

The interior of the card frame 8 is provided with a cleaning cotton 9 that cooperates with the front of the face recognition panel 1, and the surface of the card frame 8 is provided with a spraying and disinfection mechanism 10 that cooperates with the cleaning cotton 9.

[0044] It is worth noting that the protective cover 3 is inserted from the lower end of the face recognition panel 1 during installation, so that the protective cover 3 is placed on the periphery of the face recognition panel 1, thereby protecting the frame and back of the face recognition panel 1, wherein the protective cover 3 is connected and fixed to the surface of the mounting base 2 by bolts.

[0045] Further as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, it is worth noting that the spraying and disinfecting mechanism 10 includes:

[0046] A fixing base 101 is fixed to the outer surface of the card frame 8. A conduit 102 is rotatably mounted on the inner side of the fixing base 101. A plurality of nozzles 103 are fixedly mounted on the outer surface of the conduit 102. A hose 104 is fixed to the outer surface of the conduit 102. A liquid storage tank 105 is fixed to one end of the card frame 8. A water pump 106 that cooperates with the hose 104 is fixedly mounted on the top surface of the liquid storage tank 105.

[0048] It is worth noting that the water outlet of the water pump 106 is connected to the hose 104, and the water inlet end of the water pump 106 is fixed with a water inlet pipe, and the water inlet pipe extends to the inner bottom wall of the liquid storage tank 105; the top surface of the liquid storage tank 105 is fixed with a liquid inlet pipe for easy liquid addition, so that the liquid storage tank 105 can be conveniently added with cleaning and disinfecting liquid in a timely manner, and the liquid inlet pipe is equipped with a cover; through the cooperation between the nozzle 103 and the rotating adjustment component 109, the nozzle 103 swings to a certain amplitude during spraying, thereby increasing the spraying area, and at the same time can disinfect the air in front of the front of the face recognition panel 1.

[0049] Further as Figure 1 、 Figure 2 and Figure 3 As shown, it is worth noting that the rotation adjustment component 109 includes:

[0050] A wavy guide plate 1091 is fixed to one side of the protective cover 3. A support rod 1092 is fixed to the side of the card frame 8 away from the liquid storage tank 105. A roller 1093 is provided on the surface of the wavy guide plate 1091 for rolling. One side of the roller 1093 is rotatably connected to a mounting rod 1094. Two fixing blocks 1095 are fixed to one side of the mounting rod 1094. A positioning rod 1096 is fixed between the two fixing blocks 1095. A first spring 1097 is sleeved on the outer surface of the positioning rod 1096. The positioning rod 1096 movably passes through the support rod 1092.

[0051] Rectangular frame 1098, rectangular frame 1098 is fixed to the top end of the mounting rod 1094, two arc plates 1099 are arranged inside the rectangular frame 1098, one of the arc plates 1099 is fixed to the inner bottom wall of the rectangular frame 1098, and the other arc plate 1099 is slidably arranged inside the rectangular frame 1098, and a second spring 1100 is fixed on the surface of the other arc plate 1099, and the end of the second spring 1100 is fixed to the inner side of the rectangular frame 1098, and the end of the guide rod 108 is located between the two arc plates 1099.

[0052] It is worth noting that the positioning rod 1096 moves through the support rod 1092, wherein the aperture of the support rod 1092 for the positioning rod 1096 to move is slightly larger than the rod diameter of the positioning rod 1096, thereby maintaining the smooth up and down movement of the positioning rod 1096; under the elastic force of the second spring 1100, the arc plate 1099 at the upper end is pushed downward, so that the guide rod 108 is located between the two arc plates 1099, and the elastic force of the second spring 1100 provides space for the movement of the guide rod 108.

[0053] This embodiment has the following working process: the reciprocating screw rod 6 is driven to rotate by the driving motor 7, thereby driving a slider 21 to move on the reciprocating screw rod 6, and at the same time the other slider 21 slides on the limit rod 5, so that the card frame 8 slides along the surface of the face recognition panel 1, so that the cleaning cotton 9 wipes the surface of the face recognition panel 1, thereby facilitating the cleaning of dust and stains attached to its surface. After the dust and stains are cleaned once, the cleaning cotton 9 is reset, and then the cleaning and disinfecting liquid in the liquid storage tank 105 is guided into the hose 104 through the water pump 106, and then sprayed from the nozzle 103 through the conduit 102, thereby disinfecting the surface of the face recognition panel 1, and facilitating the removal of stubborn stains. The cleaning cotton 9 is then driven downward by the card frame 8, and the nozzle 103 sprays liquid to clean and disinfect the face recognition panel 1 at the same time, thereby preventing the staff from being infected by bacteria and viruses when contacting the equipment. When the card frame 8 moves, The support rod 1092 drives the installation rod 1094 to move through the positioning rod 1096, and then drives the roller 1093 to roll on the wavy guide plate 1091 through the installation rod 1094. When the roller 1093 rolls to the convex surface of the wavy guide plate 1091, the roller 1093 drives the installation rod 1094 to move upward, thereby driving the positioning rod 1096 to move upward in the support rod 1092. At the same time, the arc plate 1099 at the lower end pushes the guide rod 108 upward. The arc plate 1099 at the upper end squeezes the guide rod 108 under the elastic force of the second spring 1100, and when the arc plate 1099 at the lower end squeezes the guide rod 108 and moves upward, the guide rod 108 drives the conduit 102 to rotate a certain angle through the ring 107. When the roller 1093 rolls to the concave surface of the wavy guide plate 1091, the guide rod 108 is reset, thereby driving the nozzle 103 to rotate during spraying, thereby increasing the spraying range and the disinfection range.

[0054] Example 2:

[0055] On the basis of Example 1, according to Figure 1 、 Figure 5 、 Figure 6 and Figure 7 As shown, it is worth noting that a placement box 11 is fixed to the bottom surface of the protective cover 3, and a dustproof component 12 that cooperates with the face recognition panel 1 is provided inside the placement box 11. The dustproof component 12 includes:

[0056] A rotating shaft 121 is rotatably mounted on the inner wall of the placement box 11. A dustproof cloth 122 is fixedly wrapped around the outer surface of the rotating shaft 121. A cloth outlet hole 123 that cooperates with the dustproof cloth 122 is opened on one side of the placement box 11;

[0057] The support rod 124 is fixed to the end surface of the dustproof cloth 122. Two symmetrically distributed hanging blocks 125 are fixed on one side of the support rod 124. Two symmetrically distributed hanging holes 126 are opened on the surface of the protective cover 3 corresponding to the hanging blocks 125.

[0058] It is worth noting that when the face recognition panel 1 is not in use, the staff can pull out the dustproof cloth 122 in the placement box 11 and clamp the hanging block 125 on the support rod 124 into the hanging hole 126, thereby limiting the dustproof cloth 122 and preventing the face recognition panel 1 from being dust-proof and contamination-proof when idle.

[0059] Further as Figure 5 As shown, it is worth mentioning that a mounting bracket 13 is fixed to the bottom surface of the protective cover 3, a guide roller 14 is rotatably connected to the inner side of the mounting bracket 13, an L-shaped bracket 15 is rotatably installed on the inner side of the mounting seat 2, a base 16 is fixed to the bottom end of the L-shaped bracket 15, and four connecting holes distributed in a rectangular shape are provided on the surface of the base 16.

[0060] It is worth noting that when the dustproof cloth 122 is pulled, the dustproof cloth 122 slides on the guide roller 14, thereby reducing the friction between the dustproof cloth 122 and the edge of the protective cover 3; the face recognition panel 1 is fixed through the connecting hole on the base 16.

[0061] Further as Figure 7 As shown, it is worth mentioning that an electric telescopic rod 17 is rotatably installed on one side of the L-shaped bracket 15, and the telescopic end of the electric telescopic rod 17 is rotatably connected to the inner side of the mounting base 2. By setting the electric telescopic rod 17, the angle of the face recognition panel 1 can be adjusted, so that it is convenient for use by some taller or shorter people.

[0062] Further as Figure 4 、 Figure 5 and Figure 6 As shown, it is worth mentioning that a rotating block 18 is fixed at one end of the rotating shaft 121, which facilitates the rotation of the rotating shaft 121 through the rotating block 18, thereby facilitating the reeling of the dustproof cloth 122; the outer surface of the card frame 8 is threadedly connected to the cleaning cotton 9 with a limiting bolt 19, and the cleaning cotton 9 fixed by the limiting bolt 19 is convenient for the staff to replace regularly; the outer surface of the card frame 8 is fixed with a limiting block 20, and the hose 104 movably passes through the limiting block 20, and the limiting block 20 limits the hose 104.

[0063] On the basis of Example 1, this embodiment also has the following working process: when the face recognition panel 1 is not in use, the staff can pull out the dustproof cloth 122 in the placement box 11, and clamp the hanging block 125 on the support rod 124 into the hanging hole 126, thereby limiting the dustproof cloth 122, thereby preventing the face recognition panel 1 from being dust-proof and anti-fouling treated when idle. The rotating block 18 facilitates the rotation of the rotating shaft 121, thereby facilitating the winding of the dustproof cloth 122. When the dustproof cloth 122 is pulled, the dustproof cloth 122 slides on the guide roller 14, thereby reducing the friction between the dustproof cloth 122 and the edge of the protective cover 3. The electric telescopic rod 17 is set to adjust the angle of the face recognition panel 1, which is convenient for use by some taller or shorter people.

[0064] In summary, in combination with the two embodiments, it can be known that: the reciprocating screw 6 is driven to rotate by the driving motor 7, thereby driving one slider 21 to move on the reciprocating screw 6, and at the same time the other slider 21 slides on the limit rod 5, so that the card frame 8 slides along the surface of the face recognition panel 1, so that the cleaning cotton 9 wipes the surface of the face recognition panel 1, thereby facilitating the cleaning of dust and stains attached to its surface. After the dust and stains are cleaned once, the cleaning cotton 9 is reset, and then the cleaning and disinfecting liquid in the liquid storage tank 105 is guided into the hose 104 through the water pump 106, and then sprayed out from the nozzle 103 through the conduit 102, thereby disinfecting the surface of the face recognition panel 1, and facilitating the removal of stubborn stains. Then, the cleaning cotton 9 is driven downward by the card frame 8, and the nozzle 103 sprays liquid, cleaning and disinfecting the face recognition panel 1 at the same time, thereby preventing the staff from being infected by bacteria and viruses when contacting the equipment.

[0065] When the card frame 8 moves, the support rod 1092 drives the installation rod 1094 to move through the positioning rod 1096, and then drives the roller 1093 to roll on the wavy guide plate 1091 through the installation rod 1094. When the roller 1093 rolls to the convex surface of the wavy guide plate 1091, the roller 1093 drives the installation rod 1094 to move upward, thereby driving the positioning rod 1096 to move upward in the support rod 1092. At the same time, the arc plate 1099 at the lower end pushes the guide rod 1094 upward. 8. The curved plate 1099 at the upper end squeezes the guide rod 108 under the elastic force of the second spring 1100. When the curved plate 1099 at the lower end squeezes the guide rod 108 and moves upward, the guide rod 108 drives the conduit 102 to rotate a certain angle through the collar 107. When the roller 1093 rolls to the concave surface of the wavy guide plate 1091, the guide rod 108 resets, thereby driving the nozzle 103 to rotate during spraying, thereby increasing the spraying range and the disinfection range.

[0066] When the face recognition panel 1 is not in use, the staff can pull out the dustproof cloth 122 in the placement box 11 and clamp the hanging block 125 on the support rod 124 into the hanging hole 126 to limit the dustproof cloth 122, thereby preventing the face recognition panel 1 from being dust-proof and anti-fouling treated when idle. The rotating block 18 facilitates the rotation of the rotating shaft 121, thereby facilitating the rewinding of the dustproof cloth 122.

[0067] The driving motor 7, the water pump 106 and the electric telescopic rod 17 can be purchased from the market and equipped with a separate power supply. They are mature technologies in this field and have been fully disclosed, so they will not be repeated in the specification.
